- The principal investigator
Correct answer: The sponsor
GCP stipulates that while a sponsor may transfer duties to a CRO, the sponsor retains ultimate regulatory responsibility for the trial.
Question 108: What is the purpose of a 'first sale' valuation methodology in US customs?
- To value goods at the price paid by the US importer to the foreign seller
- To value goods at the earliest transaction price in a multi-tier supply chain, potentially lowering dutiable value (Correct answer)
- To apply a standard government-set value for goods lacking commercial invoices
- To use the manufacturer's suggested retail price as the basis for customs value
Correct answer: To value goods at the earliest transaction price in a multi-tier supply chain, potentially lowering dutiable value
First sale valuation allows importers to use the transaction price between the manufacturer and the middleman (rather than the middleman and the US importer) as the customs value, which can reduce duty liability.
Question 109: What is the 'intent-to-treat' (ITT) analysis population in a clinical trial?
- All randomized participants analyzed in their assigned treatment group regardless of actual treatment received (Correct answer)
- Only participants who received at least one dose of study drug
- Only participants who completed the full study per protocol
- Participants who met all eligibility criteria without deviation
Correct answer: All randomized participants analyzed in their assigned treatment group regardless of actual treatment received
The intent-to-treat population includes all randomized participants analyzed according to their randomly assigned treatment, preserving the benefits of randomization and reducing selection bias.
Question 110: What is an 'early termination visit' (ETV) in the context of subject retention?
- The final scheduled visit for all subjects
- A protocol-specified visit conducted when a subject withdraws from the study before completing all scheduled visits (Correct answer)
- An unscheduled visit triggered by an SAE
- An interim analysis visit
Correct answer: A protocol-specified visit conducted when a subject withdraws from the study before completing all scheduled visits
An early termination visit is conducted when a subject withdraws early, capturing remaining safety and efficacy data per the protocol.

A run-in period is a pre-randomization phase used to assess subject eligibility, compliance, washout prior medications, or establish a stable baseline.
Question 112: What is the 'randomization ratio' in a clinical trial, and why does it matter for recruitment?
- The ratio of SAEs to total enrolled subjects
- The proportion of female to male subjects
- The ratio of enrolled to screened subjects
- The allocation ratio of subjects to treatment arms (e.g., 2:1 active to placebo), which affects sample size and enrollment planning (Correct answer)
Correct answer: The allocation ratio of subjects to treatment arms (e.g., 2:1 active to placebo), which affects sample size and enrollment planning
The randomization ratio defines how subjects are allocated to treatment arms and directly impacts the sample size needed in each arm to power the trial.
Question 113: In a clinical trial, what is a 'comparator product'?
- A product used only after unblinding
- An approved or investigational product used as a reference in a controlled trial for comparison with the investigational product (Correct answer)
- A placebo tablet used only in Phase I trials
- The backup supply held at the sponsor's warehouse
Correct answer: An approved or investigational product used as a reference in a controlled trial for comparison with the investigational product
A comparator product is an approved or investigational agent used as a control against which the investigational product's effects are compared.
Question 114: What does it mean for an adverse event to be 'unexpected' in the context of SUSAR reporting?
- The event happened without warning signs
- The event occurred in fewer than 1% of subjects
- The event is unrelated to the investigational product
